Action
Final rule.
Summary
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by reports of cracking on the ejector ducts. This AD requires repetitively inspecting the left-hand (LH) side and right-hand (RH) side ejector ducts, including the exhaust bracket reinforcements and reinforcement plates, and, depending on the results, replacing any affected ejector duct. The FAA is issuing this AD to address the unsafe condition on these products.
